Title: Method for selecting kind of electronic device
Inventor: WATANABE HIROSHI
IPC: G06F9/30
Filed: 1982-02-10
Abstract: PURPOSE:To attain stable control proper to the original device even if the device codes to be applied to an input port are changed because of an accident or the like by providing a microcomputer or the like to be used for plural devices in common with a means to store and latch the device codes at the connection of a power supply. CONSTITUTION:Device codes are applied to the microcomputer 20 through latch circuits 11-13. When a rise signal generated by a resistor 14 and a capacitor 15 at the connection of the power source is applied to the latch circuits 11-13, the circuits 11-13 store the device codes applied to the input ports 1-3 and the storages are latched until the disconnection of the power supply. Therefore even if the device codes applied to the input ports 1-3 are changed by disconnection short of a harness or the like during control, the microcomputer 20 stores the device codes stored and latched by the latch circuits 11-13 at the connection of the power supply, so that the operation is always stabilized.

Title: Manufacture of electric-fusion-welded joint
Inventor: HACHIMAN KOJI
IPC: B29C65/68
Filed: 1995-02-09
Abstract: PURPOSE: To perform uniform diameter contraction at the time of fusion-welding to a connecting pipe so as to obtain excellent fusion-welding strength by making the temperature of an outer mold higher by the specific temperature or more than the temperature of a core and lower by the specific temperature or more than the fusing point of resin to injection-molding a joint, and then cooling it in refrigerant. CONSTITUTION: Resin with a linear expansion coefficient of 7×10<-5> cm/cm. deg.C or more at 23 deg.C is injected into a cylindrical cavity formed by an outer mold and a core wounded with heating wire 10b, thus forming an electric-fusion-welded joint 10. In this case, the temperature of the outer mold is made higher by 20 deg.C or more than the temperature of the core and made lower by 10 deg.C or more than the fusing point of the resin to perform injection molding, and then the joint 10 is cooled in refrigerant. The core side inner peripheral surface of the joint 10 is therefore cooled first so as to form a dense solidified layer. Since the outer peripheral surface of the joint 10 is high in temperature and cooled as it is in the rough state in the refrigerant outside of the mold, the joint 10 is cooled and hardened leaving contracted distortion on the outer mold side.  Uniform diameter contraction is thereby performed at the time of fusion-welding to a connecting pipe so as to obtain excellent fusion-welding strength.
